This is the PLCX-25.4-4996.8-UV, a Plano-Convex Spherical Lens with a diameter of 25.4 mm, sourced from CVI Laser Optics. The lens is designed for use with a wavelength of 266 nm and is uncoated.
The lens has a focal length (EFL) of 10000mm, making it suitable for applications that require long-distance focusing. The lens's geometry includes an edge thickness of 3.98 mm and a center thickness of 4 mm. The inner and outer radii are 0 mm, indicating a plano surface on one side and a curved surface on the other.
The lens is made of UVFS material, specifically identified as MAL-1965 in the material ID. This material is often used in laser applications due to its high transmission in the UV range.
